Cheng Loong Corporation will install a new circulating fluidized bed (CFB) boiler and flue gas treatment system at its flagship Houli paper mill in Taiwan, an investment planned to significantly cut the mill's coal usage, according to the technology supplier Valmet. The delivery includes a Valmet DNA distributed control system for automation.
The boiler has a fuel capacity of 107 MW and is designed for high fuel flexibility, capable of utilizing various - waste streams including RDF, SRF, and TDF - as well as biomass. The flue gas treatment system is configured to achieve low emissions and includes a pre-separator, additive injection, a dry system, bag house filters, and an SCR unit. The CFB technology is optimized for high overall thermal efficiency.
The primary application for the boiler is the production of electricity and heat for the Houli mill's operations. This system will also enable the mill to efficiently handle all of its solid waste on-site.
Cheng Loong Corporation estimates the new boiler will reduce the mill's annual CO₂ emissions by 48,000 tonnes and increase the proportion of non-fossil fuels in the mill's energy mix to more than 30%.
